    Fog Lights CTS 2009

    I currently have a 2009 CTS Sedan and want to add fog lights as a gift for my spouse. I do not know where to start. I went to the dealership and was told to find a place that sells a kit because Cadillac does not make one for this model and if I brought all of the separate parts it will be very costly. Any suggestions would be greatly appreciated.

    You can start by doing a search on the forum or google..this has been covered numerous times.
    It's possible and not very expensive.
    There are threads here with part numbers you'll need. Then if you're handy you can install them yourself again there is a thread on how to remove front bumper and etc.
    I think it cost me around 200 -250 for parts. install I did myself.
    Basic run down - fog light housing (got a pair for 100)
    -chrome cts bezels (I think I paid about 35 for each)
    -generic fog light wiring kit with a switch (15 maybe)
    Wires that connect the fogs to wiring kit 15 I think

    Rockauto is your best bet for prices.

    Do you have any pics of your finished product? And i'm assuming this in the area where the insert is at also? Do you think this will work for a 2008?

    On Ebay under CTS fog lights, Cadillac Bling has the whole kit for about $350.

    This topic has been covered a few times, what I haven't seen here is how to use a factory switch (multiway signal switch). I took me several months to find out how to get it to work. Basically, the factory switch sends a signal to the Body Control Module, which in turn triggers the factory relay. Once the factory switch is installed, the instrument panel indicator light works (i.e. - electrics are in place) However, there is no wiring from the BCM to the front fuse box. Basically, it takes a bit of work but can be done.

    Did you have to get the computer programmed? I found the lines at the bcm and ran the wiring but the output at the bcm doesn't turn on.

    Re: Fog Lights CTS 2009

    Yes the computer has to be flashed to inform it that the fog lights are installed. After much consideration, I am going the seperate switch route. First, it gives you fogs on both low and high beams. Second, don't want to screw with the steering column installing a new control lever. Third, don't want to mess with the BCU. Fourth, one less annoying lighted symbol on the dash. Obviously, Glyn Morgan has installed his. I would appreciate it if he would describe in detail how he was able to do it. Thanks.

    Does anyone have, or know how to gain access to written or video instruction on how to install fog lights properly? I have a 2009 cts, and so far I'm not having any success with my install.

    Re: Fog Lights CTS 2009

    i did a complete fog switch, used factory switch and all. i had a helluva time and it ended up costing about $1000, but that was because of some crazy electric issues that may or may not have happened because of the fogs. It's a simple concept though. buy the turn signal that has the fog switch. its like $35 from rockauto. i put it in, and the computer instantly knew it was a fog light switch. turn the switch on, it shows the fog icon on the dash. buy the chrome bezels, then buy the actual light housings. i ran power wire from the lights to the fuse block. and like a guy said before, the only thing lacking was a wire from the BCM to the fuse block. i bought the little GM pin that plugs into the BCM, figured out which pin it needed to be plugged into, then ran that wire all the way through the firewall to the fuse block and installed a regular 12v relay next to the fuse block (under the removeable black cover on the left side). the relay needs power from the battery, a ground, 1 leg to the lights, and then the single wire from the bcm. i had it all hooked up, had a problem, brought it to the dealer for them to "finish the job" and they ended up burning up the fuse block, then the bcm, and ended up being a $700+ repair. i know it was nothing i did, i work with wiring alot and i'm no car pro but i'm no low voltage dummy either. anyway, you could try that route, do as much as you can and then just bring it to the caddy dealer and pay em $100-150 to finish it up for you, i'm sure the same wont happen to anyone else...it was just my luck

    ----------

    the computer did not need to be flash i don't think, but i could be wrong. it was in the shop for a month figuring out my electric issue! but as far as the bcm pin, you will have to do reasearch, i saved A WHOLE LOT of forums and printed everything out and it took me about 4 months to get it all bought/installed/researched/and completed. i think it looks awesome. it would deff have been worth the money if i hadn't run into the random electric issue.
